AbstractThree bathymetric maps of Rankin Inlet area where produced following a short training provided to three staff members of the Nunavut Research Institute by Canada Centre for Remote Sensing (CCRS) scientists during the summer of 2009. The objective of this technology transfer exercise was to assist staff from Nunavut Research Institute to apply the methodologies in Nunavut communities where drinking water supply is at risk due to a declining supply and a changing climate.
With support from Indian and Northern Affairs Canada (INAC) from 2008, a small team of scientists at the Canada Centre for Remote Sensing (CCRS) is involved in a project to help characterize the water supply of Nunavut communities. This is a complex task involving the delineation of watersheds and estimation of the water volume retained by the supply lake of the community. To estimate this water volume, a bathymetric map is produced based on field surveys using a depth sounder equipped with a GPS.
CCRS developed a low cost and easy to use technique to enable such depth surveys to be easily and rapidly carried out. The training provided to Nunavut Research Institute was aimed to allow Nunavut professionals to produce lake depth maps with low cost and easy to use tools and software. The three depth maps were produced under the ''Enhancing Resilience in a Changing Climate Program'' of the Earth Sciences Sector, Natural Resources Canada. These maps were created and from the interpolation of thousands of depth survey points acquired by Nunavut Research Institute (NRI) and the Department of Community & Government Services (C&GS) staff between
September 29th and October 4th 2009. Three large format paper prints were sent to the Community and Government Services, Kivalliq Region, and Rankin Inlet in March 2010, followed by a second set in April 2010.
This document describes the digital dataset provided to the Community and Government Services Rankin Inlet Office for each of the three water bodies: Nipissar Lake, First Landing Lake, and a bay in Little Meladine Lake.
